The Central Limit Theorem makes the normal distribution particularly useful. This applet allows users to drag sliders to change the mean and standard deviation of the normal distribution. The applet ...

As with all probability distributions, the Normal Distribution describes how the values of your data are distributed.

In any normal distribution, there are fixed probabilities for intervals around the mean based on multiples of the standard deviation of the distribution. In particular, about 2/3 of measurements ...

This graph represents the probabilities associated with the standard normal distribution and the standard ... at the graph and see it is a -1 standard deviation. Why is it -1?

In this sense, the two parameters, the mean and the standard deviation, completely describe a normal distribution. The normal ... Determining the probabilities for given values and the values for ...
